Worked on the Submitty repository to enhance JavaScript code quality and maintainability by standardizing global variable declarations and removing scattered ESLint disable comments across several front-end modules. Focused on non-functional improvements, the changes ensured ESLint compliance in files such as forum.js, docker_interface.js, latedays.js, plagiarism.js, and user-profile.js. By introducing proper /*global*/ declarations and eliminating legacy lint suppressions, the work reduced the risk of runtime issues from undeclared variables and established a cleaner codebase for future refactoring. Utilized JavaScript and ESLint to streamline onboarding and development velocity by minimizing lint-related blockers in the front-end codebase.
